mod_roster: pass correct username to roster-item-removed
The other invocations use it that way, and the only listener in trunk
which uses it (in mod_presence) expects it that way.
Passing the username of the JID from the removed entry causes incorrect
unavailable presence stanzas to be sent, allegedly kicking people off
MUCs.
Fixes #1121.
